Proper selection helps balance quality and cost while matching local business needs (such as corporate correspondence, e-commerce packaging, or premium invitations).

|---|---|---|
| Size Specifications | DL (220×110mm), ZL (230×120mm), C5 (229×162mm), C4 (324×229mm) | DL and ZL are the most popular in China for business letters, invoices, and notices; C4 fits unfolded A4 documents; tolerance usually ±1mm to avoid mailing returns |
